    • Saturated, aminated alkoxylated polymers having a high degree of maintain and saturation can be obtained by reductive amination of an alkyoxylated liquid polymer obtained by alkoxylating a hydroxyl-terminated polybutadiene (HTPB) with one or more alkylene oxides having at least three carbon atoms to provide secondary terminal hydroxyl groups, by contacting the alkoxylated liquid polymer is contacted with hydrogen and ammonia in the presence of a catalyst whose active components are nickel oxide, copper oxide, chromium oxide and molybdenum oxide, the molar ratio of hydrogen to ammonia to secondary hydroxyl groups on the alkoxylated liquid polymer being at least 50 : at least 10:1.
      Preferred products include saturated, aminated alkoxylated polymers of the formula:

      wherein each R is independently alkyl of 1 to 4 carbon atoms;
      each n is independently from 1 to 100; and
      x, y and z are numbers,
      the number average molecular weight of the hydrocarbon backbone being from 200 to 5000.
